Treatment for Apraxia of Speech in Nonfluent Variant Primary Progressive Aphasia
There is a growing body of literature examining the utility of behavioral treatment in primary progressive aphasia (PPA). There are, however, no studies exploring treatment approaches to improve speech production in individuals with apraxia of speech (AOS) associated with the nonfluent variant of PPA. The purpose of this study was to examine a novel approach to treatment of AOS in nonfluent PPA...
متن کاملWhy are patients with progressive nonfluent aphasia nonfluent?
OBJECTIVE To investigate the cognitive and neural basis for nonfluent speech in progressive nonfluent aphasia (PNFA). BACKGROUND Nonfluent speech is the hallmark feature of PNFA, and this has been attributed to impairments in syntactic processing, motor-speech planning, and executive functioning that also occur in these patients. Patients with PNFA have left inferior frontal atrophy. METHOD...
متن کاملTeaching NeuroImages: Nonfluent variant primary progressive aphasia
A 66-year-old woman presented with 4 years of progressive speech difficulty. She had nonfluent speech with phonemic errors but intact single-word comprehension and object knowledge. Her grammar was impaired in both speech and writing, and she exhibited orofacial apraxia. A clinico-radiologic (see figure) diagnosis of nonfluent variant primary progressive aphasia was made. Nonfluent variant prim...
متن کاملAnatomical correlates of early mutism in progressive nonfluent aphasia.
Patients with progressive nonfluent aphasia (PNFA) can become mute early in the course of the disease. Voxel-based morphometry showed that PNFA is associated with left anterior insula and inferior frontal atrophy. In PNFA with early mutism, volume loss was more prominent in the pars opercularis and extended into the left basal ganglia. Damage to the network of brain regions involved in both coo...
متن کاملPrimary progressive aphasia: a comparative study of progressive nonfluent aphasia and semantic dementia.
Primary progressive aphasia (PPA), a degenerative disorder, is often misdiagnosed as Alzheimer's disease. Its subtypes, semantic dementia (SD), and progressive nonfluent aphasia (PNFA), are often difficult to differentiate from each other. Our objective was to highlight the differences in the language profiles of patients with SD and PNFA. To bring out these differences, we report two patients ...
